Application filed March 3, 1915. Serial No. 11,865.

To all whom it may concern:

Be it known that I, O'rro A. PETERSON, a citizen of the United States, residing at Stoughton, county of Norfolk, State of Massachusetts, have invented an Improve ment in Hinged Lasts, of which the following description, in connection with the accompanying' drawing, is a specification, like characters on the drawing representing like parts. r

This invention relates to hinge lasts and has for its object to provide a hinge last having a novel hinge device which is very simple in construction and inexpensive to manufacture, which can be easily applied to the two parts of the last and which will.- operate automatically to lock the last either in extended or collapsed position while permitting the heel portion of the last to be freely swung from one to the other position and which has other features and advantages, all as. will be more fully hereinafter described.

In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims.

In the drawings, Figure 1 is a side view of a last embodying my invention; Fig. 2 is a vertical central section of the last showing it collapsed; Fig. 3 is a section on theline m;v, Fig. 1; ig. 4 is a view of the connecting member; Fig. 5 is a view of the pivot pin.

In the drawings 1 designates the fore part of the last and 2 the heel part thereof, the

latter being shown as having the last-pinrecei-ving socket 3, as usual, in hinge lasts.

My improvements consist in a hinge con nection uniting the fore part and heel part of the last which involves a resilient connecting member that holds and locks the heel part in either its extended or collapsed position, that is, either in the position shown in Fig. 1 or that shown in Fig. 2. The connecting member is so constructed that it will be extended during the initial swinging movement of the heel portion of the last in either direction and contracted duringthe final swinging movement, the resiliency of the connecting member thus acting to hold the last in either its extended or collapsed condition, In the illustrated embodiment of my invention this connecting member is shown at 4: andit is in the form of a curved plate of metal or other suitable material which is resilient in a longitudinal d1rection.' The meeting ends of the heel and fore part of the last are provided with slots 5 and 6 in which the ends of the con necting member are received, and said connecting member is secured at its ends to the heel and fore part of the last in any suitable way as by means of pins 7 and 8 that extend transversely through the parts of the last and through openings 9 formed in the ends of the connecting member. The two members of the last are provided with means to hold them in proper position relative to each other during the turning movement of the heel portion of the last so that the swinging movement of the heel portion w1ll be about its properaxis. Any suitable means for this purpose may be employed. Thatherein shown constitutes a pivotal pin 10 which rests in two half recesses 11, 12 formed in the heel and toe portions of the last, respectively.

The pins? and 8 are so situated relative to the pivotal pin 10 that whenv the last is extended, as shown in Fig. 1, a line joining the pins 7 and 8- will be below the center of the pin 10, while when the last is collapsed, as shown in Fig. 2, said line joining the pins 7 and 8 will be above the center of the pin 10.

As the heel portion 2 swings from its extended to its collapsed position the pin 7 will move in the arc of a circle having for its center the center of the pin 10. Consequently during the initial swinging movement of the heel part 2 from either of its positions to the other position and until the line joining the pins 7 and 8 is in line with the center of the pin 10, said pin 7 will have a slight movement away from the pin 8. During the completion of the movement of the heel part 2 in either direction the movement of the pin 7 will be slightly toward the pin 8. As a result when the heel part 2 is moved from its extended to its collapsed position or vice versa, the initial movement thereof results in an extension or elongation of the connecting member at and the final movement results in a contraction of said member -l. The member l, therefore, serves as a lock to hold the last either in its extended or its collapsed position, but by applying sufiicient force to the last the heel part can be swung from one position to the other.

A last embodying the above construction is extremely simple as the connection between the parts involves merely the connecting member 4 with suitable means for securing it to the two parts of the last and some suitable means, such as the pin 10, to constitute the fulcrum about which the heel part turns. The resiliency of the member 4 is such as to securely hold the two parts of the last in their relative positions and the construction shown is one providing ample resistance to any torsional or twisting strain between the two parts of the last or any lateral strain to which the last may be subjected.

The connecting member 4 will preferably be so constructed that it will be under some strain when the last is either straightened or collapsed, and hence in either of these two positions the member 4 operates to hold the two parts of the last firmly against each other and to prevent any lost play the two parts of the last are, therefore, yieldingly held in contact with each other in either of the two positions shown in Figs. 1 and 2, and the resiliency of the member 4 is suflicient to take up any looseness which mavoccur due to. the wearing of the pin 4 or the meeting faces of the two members.

While I have illustrated herein a selected embodiment of my invention I do not wish to be limited to the constructional features shown. 1

I claim:

1. In a hinge last, the combination with a fore part, of a heel part capable of having a swinging movement relative to the fore part and a resilient connecting member connected to both parts of the last and shaped to hold them yieldingly in either their ex-- tended or collapsed position.

2. In a hinge last, the combination with a fore part and a heel part, of connecting means comprising means constituting a fulcrum about which the heel part turns and a longitudinally resilient connecting member connected to both the heel part and the fore part of the last at points which are in a line at one side of the axis of movement of the heel part when the last is extended and at the other side of said axis when the last is collapsed.

3. In a hinge last, the combination with a fore part and a heel part, one of which has a groove extending transversely thereof. of means associated with the other part and occupying said groove and constituting a fulcrum about which the heel part turns, and a longitudinally resilient connecting member secured to both the heel part and the fore part and shaped to hold the last yieldingly either extended or collapsed.

4. In a hinge last, the combination with a fore part and a heel part, one of which has a groove extending transversely thereof, of means associated with the other part and occupying said groove and constituting a fulcrum about whichthe heel part turns,

and a resilient connecting member con- I said slots and connected at its ends to the heel part and fore part, respectively, at points which are in a line at one side of the center of the fulcrum pin when the last is extended and atthe other side when the last is collapsed.

- 6. In a hinge last, the combination with a fore part, of a heel part capable of having a swinging movement relative to the fore part, and a longitudinally-resilient member connected to both the parts at points which are in a line at one side of the axis of the swinging movement of the heel part when the last is extended and on the other side of said axis when the last is collapsed whereby'said member will hold the parts yieldingly in. either extended or collapsed position.

7. A last comprising a heel part and a fore part having a common fulcrum point and being arranged and constructed to turn about said point into extended and collapsed position, and a longitudinally resilient member operatively connected to said parts at points which are in a line on one side of the fulcrum when the last is extended and on the other side of the fulcrum when the last is collapsed, said member being arranged to hold the last parts resilicntly in either their extended or collapsed position.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

OTTO A. PETERSON.
